Hi,
In my limited experiences with molding, it seems the cooling water flow rate can be a very important process parameter. A blockage in a cooling line, or a weak/defective pump, can significantly affect the rate of heat removal in a mold and royally screw up dimensions and other stuff.
So why don't any of the TCU's I've ever come across have a flow meter built into them? Wouldn't it be a good idea to read and monitor flow rate just as you read and monitor the water temperature? Instead we seem to drag out the flow rate meter when its time to do some troubleshooting/firefighting, usually because we have already shipped bad parts.
Do they exist, and I just have never seen one? Should we put a bug in some peoples ears to develop & market one?
